fluosilicic acid uses

Fluosilicic acid definition, an unstable acid, H2SiF6, known only in its colorless, poisonous, fuming aqueous solution or in the form of its salts: used chiefly as a wood preservative, a disinfectant, and as a hardening agent in the manufacture of ceramic ware, cement, and concrete. Used in water fluoridation, in hardening cement and ceramics, as a wood preservative. 1.8.3 Sodium Fluoride: Sodium fluoride is a powder, or crystals, or a The report on Fluosilicic Acid Market provides qualitative as well as quantitative analysis in terms of market dynamics, competition scenarios, opportunity analysis, market growth, etc. Fluosilicic Acid, chemically written as F6H2Si, is a liquid chemical that is corrosive and requires the right pump to accommodate it. Used as source of fluoride. a. Where a substantial concentration of fluosilicic acid (more than 22% H 2 SiF 6) and a high yield is required, two absorption towers may be used together. a. mixing the crude gypsum with an aqueous fluosilicic acid (hydrofluosilicic acid, silicofluoric acid (H 2 SiF 6)) solution at about 160°-195° F. to obtain a liquid phase and a solid phase; b. separating the liquid phase from the solid phase (e.g., by filtration, centrifugation, or decantation) while maintaining the temperature of the liquid phase within a range of about 160°-195° F.; for the forecast year up to 2029. Reacts with water and steam. Compare Products: Select up to 4 products. Details of the supplier of the safety data sheet PCS Sales (USA), Inc. 1101 Skokie Blvd. It is used to convert aluminum ore into aluminum metal, to refine lead, as a reagent in organic synthesis, etc. Relevant identified uses of the substance or mixture and uses advised against Use of the substance/mixture : Industrial use 1.3. These corrosion data are mainly based on results of general corrosion laboratory tests, carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen). Fluosilicic acid concentrates in pools and spas over time while water evaporates. About 41,200, 4,700, and 13,200 tons of byproduct fluorosilicic acid were sold for water fluoridation, AlF3 production for the aluminum industry, and for other uses, such as sodium silicofluoride production, respectively. Such a configuration is recommended when the phosphoric acid has a concentration of up to 42-46% P 2 O 5.

Fluosilicic acid - Identification, toxicity, use, water pollution potential, ecological toxicity and regulatory information Note : See Working with the Information on this Page section below for important notes about this data. Fluosilicic acid (FSA) is obtained in large quantities as a by-product from wet phosphoric acid and phosphate fertiliser plants. It has a strong smell and is commonly found in fertilizers, and it is also often added to water, as fluosilicic acid is present within a wide-range of industries. 4.2 Uses of Fluosilicic acid. Fluosilicic Acid Fluosilicic acid is a corrosive, catalytic, water-reactive, inorganic acid that can be converted into a variety of hexafluorosilicate salts. All other chemicals used were reagent grade. fluorine-bearing chemicals". This substance is used in the following products: biocides (e.g. Define Fluosilicic. Search results for fluorosilicic acid at Sigma-Aldrich. 4.2 Uses of Fluosilicic acid. It reacts violently with bases and is corrosive. Attacks glass and stoneware. Fluorosilicic acid is also used to make aluminum fluoride for the aluminum industry. If analyses are desired, the following protocol is recommended. disinfectants, pest control products) and … Fluorosilicic Acid, Hexafluorosilicic Acid, Fluosilicic Acid or FSA is also an involuntary byproduct of the phosphoric acid industry that is normally being neutralized and disposed with the phosphogypsum or in a dedicated area. Purity Requirements: Analyses of available grades of fluosilicic acid show the presence of arsenic and lead but at levels far below that which would necessitate RMIC values based on a maximum dosage of 1.2 mg of fluoride ion/liter. These technologies are well proven over 50 years at a wide range of capacities and have been sold world-wide. The major use of sodium hexafluorosilicate and fluorosilicic acid is as fluoridation agents for drinking water. The slag samples were leached using fluosilicic acid (H2SiF6), a byproduct of the fertilizer industry. Consumer Uses . 1. Fluosilicic synonyms, Fluosilicic pronunciation, Fluosilicic translation, English dictionary definition of Fluosilicic. The first process known for manufacturing (LBD) aluminium fluoride from fluosilicic acid was patented by Chemie-Linz, Austria and many plants were built based on this technology or similar technologies. Corrosive to metals and tissue. Buss ChemTech is the market leader for fluorine chemical process technologies. A chemical profile of the acid byproduct used is presented in table 2. hydrofluosilicic acid, sodium fluoride and sodium silicofluoride, presently used for fluoridation of water. See more. Both the fumes and very short contact with the liquid can cause severe and painful burns. Fluorosilicic acid appears as a colorless fuming liquid with a penetrating pungent odor. Attacks many metals. Fluosilicic acid is recovered when stack gases are scrubbed during the processing of phosphate fertilizers. This process uses the direct neutralization of the fluosilicic acid with alumina hydroxide in … The solution of fluosilicic acid and ammonium fluosilicate, or ammonium fluosilicate alone if ammonium fluoride is used for scrubbing, is reacted with ammonia thereby converting the fluorine-containing salts to ammonium fluoride and regenerating the colloidal silica for recycle to the phosphoric acid concentrators. The major use of sodium hexafluorosilicate and fluorosilicic acid is as fluoridation agents for drinking water. Composed of, or derived from, silicon and fluorine. By recovering by-product fluosilicic acid from fertilizer manufacturing, water and air pollution are minimized, and water authorities have a low-cost source of fluoride available to them.” 1.3 Details of the supplier of the safety data sheet Company : Central Drug House (P ) Ltd 7/28 Vardaan House New Delhi -110002 INDIA Sources/Uses Used as a chemical intermediate, a disinfectant, a water fluoridating agent, a wood preservative, a masonry and ceramic hardener, and a glass additive; it is also used to treat hides and skins, to electroplate chromium, and to electrolytically refine lead; [HSDB] Used in technical paints, oil well acidizing, and to remove mold, rust, and stains from textiles; [NTP] Define hydrofluosilicic acid. Fluosilicic acid is the feedstock for "virtually all organic and inorganic fluorine-bearing chemicals".
